140 AB bc is .485. Partition is .434. The same load (47.5 gr Big Game) generates slightly (30 fps or so) less velocity in the AB compared to the PT. So here’s the math, velocity only:
140 PT, .434, 2890 fps
300 yards 2280
400 yards. 2095
500 yards. 1919
600 yards. 1752
140 AB, .485, 2860 fps
300 yards. 2314
400 yards. 2147
500 yards. 1986
600 yards. 1833
81 fps at 600 yards isn’t impressive.

Good stuff. What's the wind drift numbers for those?
